The air outlet frame assembly 2 and the air conditioner 100 according to the embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1, the air-out frame assembly 2 according to the embodiment of the present invention includes an air-out frame 21.

As shown in fig. 1, fig. 2 and fig. 5, the air-out frame 21 is rotatably disposed at the air outlet 101 of the airflow channel 113, the air-out frame 21 has an air-out channel 23, the air-out channel 23 has a first end 231 and a second end 232 along the airflow flowing direction, and the cross-sectional area of the first end 231 is larger than that of the second end 232.

Therefore, the first end 231 is located at the upstream of the second end 232 or the second end 232 is located at the upstream of the first end 231 in the airflow flowing direction by rotating the air outlet frame 21, and as shown in fig. 3, when the first end 231 is located at the upstream of the second end 232, because the cross-sectional area of the second end 232 is smaller than that of the first end 231, the effect of air gathering can be achieved, and the purpose of improving the air supply speed and the air supply distance can be achieved; as shown in fig. 4, when the second end 232 is located at the upstream of the first end 231, the cross-sectional area of the first end 231 is larger than that of the second end 232, so that the wind can be diffused, and the purposes of reducing the wind speed and making the wind outlet flexible are achieved.

According to the utility model discloses air-out frame subassembly 2, through making the rotatable establishing in air outlet 101 department of air-out frame 21, and make the cross-sectional area of the first end 231 of ground air-out passageway 23 be greater than the cross-sectional area of second end 232, through the position relation of adjustment first end 231 and second end 232 on the flow direction of air current, can realize improving the purpose of air supply speed and air supply distance or realize slowing down wind speed, the gentle and agreeable purpose of air-out, satisfy user's different demands.

Further, as shown in fig. 5, the cross-sectional area of the air outlet channel 23 gradually decreases in the direction from the first end 231 to the second end 232. Therefore, the better guiding effect on the air flow can be realized, the air flow has a better wind gathering effect or diffusion effect, and meanwhile, the noise in the air flow flowing process can be reduced.

Alternatively, as shown in fig. 5, along the airflow flowing direction, the length (the length in the up-down direction shown in fig. 6) of the air outlet channel 23 is the same, the width (the width in the left-right direction shown in fig. 5) of the first end 231 is greater than the width of the second end 232, and the width of the air outlet channel 23 gradually decreases in the direction from the first end 231 to the second end 232. From this, the cross-sectional area of the first end 231 can be larger than that of the second end 232, and the cross-sectional area of the air outlet channel 23 is gradually reduced in the direction from the first end 231 to the second end 232, which is beneficial to simplifying the structure and the processing technology of the air outlet frame 21, and can realize better guiding effect on the air flow, so that the air flow has better wind gathering effect or diffusion effect, and meanwhile, the noise in the air flow flowing process can be reduced.

Of course, the utility model discloses be not limited to this, along the air current direction of flow, the width of air-out passageway 23 can be the same, and the length of first end 231 is greater than the length of second end 232, and in the direction of first end 231 to second end 232, the length of air-out passageway 23 reduces gradually.

Further, as shown in fig. 5, at least one of the two side walls of the air outlet channel 23 in the width direction is an arc-shaped surface or a plane. Therefore, the structure of the air outlet frame 21 can be simplified, the guiding effect of the side wall of the air outlet channel 23 on the air flow can be increased, and the noise in the air flow flowing process can be reduced.

Therefore, an air outlet gap can be defined between the outer side wall of the air outlet frame 21 and the inner peripheral wall of the air outlet 101, and the condensation phenomenon caused by inconsistent temperatures of the inner side and the outer side of the air outlet frame 21 can be avoided. Further, as shown in fig. 5, two outer side walls of the air-out frame 21 in the width direction are arc-shaped surfaces to guide the airflow to flow toward the direction close to the center of the air outlet 101.

Further, as shown in fig. 5, two outer side walls in the width direction (left and right direction shown in fig. 5) of the air-out frame 21 are arc-shaped surfaces protruding toward a direction away from the air-out channel 23. Therefore, the airflow flowing out from the gap between the two outer side walls in the width direction of the air-out frame 21 and the inner peripheral wall of the air outlet 101 can better flow towards the center of the air outlet 101.

In some embodiments of the present invention, as shown in fig. 5, the air outlet frame 21 includes a first side plate 211 and a second side plate 212 spaced apart in a width direction (a left-right direction shown in fig. 5) of the air outlet channel 23, at least one of the first side plate 211 and the second side plate 212 has a cavity 2121, and the cavity 2121 extends along a length direction of the air outlet frame 21. Thereby, the heat insulation effect of the first side plate 211 and the second side plate 212 can be improved. Further, the cavity 2121 extends along the length direction (up-down direction as shown in fig. 6) of the corresponding first side plate 211 or second side plate 212. Thereby, the heat insulation effect of the first side plate 211 and the second side plate 212 can be further improved.

As shown in fig. 6, the air outlet frame 2121 further includes a top plate 213 and a bottom plate 214, the top plate 213 is connected to one end of the first side plate 211 and the second side plate 212 in the length direction (in the up-down direction shown in fig. 6), the bottom plate 214 is connected to the other end of the first side plate 211 and the second side plate 212 in the length direction, the top plate 213, the first side plate 211, the second side plate 212, and the bottom plate 214 jointly define the air outlet channel 23, the first side plate 211 and the second side plate 212 are symmetrical in shape, and the top plate 213 and the bottom plate 214 are identical in shape.
